VP Lamp information

Hi :
Dear friends,
I am searching for information about video projectors. And I want to know why two devices with same lamp have a different light output. In fact I’d like to know is there any special parameters which affects the out put although the devices have similar lamps?
I’ll be glad if anybody has technical information about video projector’s lamp help me on this case.
